NWA 11220 Martian Meteorite: 3D Petrofabric Data via X-ray Microtomography

Seven segmented images and associated tabular data from X-ray computed microtomography (XCT) analysis of Martian breccia NWA 11220. The dataset includes raw image stacks, processed segmentation reports, and particle analysis results for three distinct mineral phases across four samples. A. Goodwin from the University of Manchester produced this data as supporting information for a published research paper.

Use Cases

• Quantifying mineral phase proportions within igneous clasts based on segmented images and particle analysis data.
• Analyzing 3D fabric and clast orientation from manually and automatically segmented proto-breccia clast data.
• Correlating mineralogical composition from Raman spectroscopy and SEM/EDS maps with 3D structural data from XCT scans.

Strengths

• Includes raw, unprocessed image stacks for multiple samples, allowing for independent analysis.
• Provides data from multiple analytical techniques (XCT, Raman, SEM/EDS) for cross-validation.
• Contains both automatic and manual segmentation results for comparative assessment.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
